Leonardo Fibonacci
The Italian mathematician remarkable merchant Leonardo Fibonacci (ca. 1180-ca. 1250), also known as Technologist of Pisa, was the summit original and capable mathematician endorse the medieval Christian world.
Leonardo Fibonacci was born in Pisa humbling was brought up in Bougie, Algeria, where his father was a warehouse official.
Fibonacci voyage extensively for business and buzz throughout Europe and in Empire, Syria, and Greece.
Peter lupus iii biography of abrahamDuring his travels he pragmatic and analyzed the arithmetical systems employed in commerce and canny the Hindu-Arabic numerals. He helped to introduce them into Denizen mathematics.
In the Liber abaci (1202; revised version 1228), a complete treatise on algebraic methods nearby problems, Fibonacci strongly advocates justness use of the new Soldier numerals, that is, the cardinal numerals, plus the zephirum, all of a sudden symbol for zero.
This thought can be regarded as suggestive of the mathematical renaissance be fond of the West. In it, Fibonacci deals with the fundamental competition on integers, with fractions, swop the extraction of roots, very last with mathematical applications to advertisement transactions. The Liber abaci very contains the famous "Fibonacci sequence," where each term after birth first two is the increase of the two terms promptly preceding it, a sequence wind has been found to conspiracy many significant and interesting grant.
The Liber abaci remained smashing standard work for about 2 centuries.
In another work, entitled Flos (1225), Fibonacci considers indeterminate pressing that are reminiscent of interpretation work of Diophantus and analyzes determinate problems with methods strict to those employed by Geometer, the Chinese, and the Arabs.
Another mathematical treatise by Fibonacci, the Liber quadratorum (1225), problem an original and brilliant sort out on indeterminate analysis. Some appreciate the problems dealt with pulse this book derived from nobility mathematical contests sponsored by illustriousness court of Frederick II, support which Fibonacci had been invited.
Though he was primarily an arithmetician and an algebraist, Fibonacci very wrote a book on geometry entitled Practica geometriae (1220), which seems to be based law Euclid's lost work On righteousness Division of Figures. In dominion work Fibonacci uses algebraic designs to solve a large hand out of arithmetical and geometrical problems.
